Abstract
Abstract An end loaded display carton is formed from a cut and scored blank of paperboard or the like that is preglued and shipped in a generally flat folded condition. The carton, when squared, is of essentially parallelopiped configuration with spaced front and rear walls connected by two outer side walls, and includes a central compartment for receiving a product and a header member at one end thereof. The central compartment is defined by a pair of inner side wall panels that are spaced inboard of and parallel to the outer side walls and which extend for substantially the entire length of the carton. When the carton is squared from its generally flat folded condition to its product receiving parallelopiped condition, the header member at one end thereof is automatically oriented over the central compartment portion of the carton.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
An end loaded carton of generally parallelopiped configuration, formed from a single blank of paperboard or the like comprising, spaced outer front and rear walls separated from one another by a pair of outer side walls, end closure flaps for each end of the carton, and an inner product receiving compartment, said inner compartment comprising a pair of inner side wall panels spaced apart and inboard of said outer side walls and adhered to the said outer front and rear walls, the improvement comprising a first inner compartment header panel foldably attached to an end of one of said inner side wall panels along a diagonally oriented score line and adapted for automatic orientation over the end of said inner compartment when said carton is squared for loading, by the initial abutment of a lower edge of said header panel against the inside of said rear wall, said abutment causing the concomitant rotation of said header panel about its diagonal fold line.
Claim 2
Dependent Claim
162 words
An end loaded carton of generally parallelopiped configuration, formed from a single blank of paperboard or the like comprising, spaced outer front and rear walls separated from one another by a pair of outer side walls, end closure flaps for each end of the carton, and an inner product receiving compartment, said inner compartment comprising a pair of inner side wall panels spaced apart and inboard of said outer side walls and adhered to the said outer front and rear walls, the improvement comprising a first inner compartment header panel foldably attached to an end of one of said inner side wall panels along a diagonally oriented score line and adapted for automatic orientation over the end of said inner compartment when said carton is squared for loading, by the initial abutment of a lower edge of said header panel against the inside of said rear wall, said abutment causing the concomitant rotation of said header panel about its diagonal fold line.
Claim 3
Dependent Claim
25 words
The carton of claim 1 wherein the width of said first header panel is greater than the width of its attached inner side wall panel.
Claim 4
Dependent Claim
25 words
The carton of claim 2 wherein the length of said first header panel is equal at least to the space between said inner sidewall panels.
Claim 5
Dependent Claim
34 words
The carton of claim 3 wherein said first header panel abuts and lies in contact with the end of the other of said inner side wall panels when the carton is squared for loading.
Claim 6
Dependent Claim
30 words
The carton of claim 1 wherein a second inner compartment header panel is foldably attached to the end of the other inner compartment side wall opposite said first header panel.
Claim 7
Dependent Claim
27 words
The carton of claim 5 wherein said first and second header panels each have a width greater than the width of their attached inner side wall panels.
Claim 8
Dependent Claim
28 words
The carton of claim 6 wherein the lengths of said first and second header panels is sufficient to overlap one another when the carton is squared for loading.
Claim 9
Dependent Claim
188 words
A carton assembly for the end loading of products in a centrally located inner compartment thereof comprising, a one piece blank provided with a front wall having end closure flaps attached at each end thereof, and extending from one side thereof and successively joined thereto by parallel substantially vertical fold lines, (a) a first outer side wall; (b) a rear wall panel; (c) a second outer side wall; (d) a first glue flap; (e) a first inner compartment side wall; (f) an inner compartment back panel; (g) a second inner compartment side wall; (h) a second glue flap; and, (i) a first header panel foldably attached to one upper end of said second inner compartment side wall along a diagonally oriented fold line at an interior angle of at least about 30° with the horizontal and adapted for automatic orientation over the end of said inner compartment when said carton is squared for loading by the initial abutment of a lower edge of said header panel against the inside of said rear wall, said abutment causing the concomitant rotation of said header panel about its diagonal fold line.
Claim 10
Dependent Claim
188 words
A carton assembly for the end loading of products in a centrally located inner compartment thereof comprising, a one piece blank provided with a front wall having end closure flaps attached at each end thereof, and extending from one side thereof and successively joined thereto by parallel substantially vertical fold lines, (a) a first outer side wall; (b) a rear wall panel; (c) a second outer side wall; (d) a first glue flap; (e) a first inner compartment side wall; (f) an inner compartment back panel; (g) a second inner compartment side wall; (h) a second glue flap; and, (i) a first header panel foldably attached to one upper end of said second inner compartment side wall along a diagonally oriented fold line at an interior angle of at least about 30° with the horizontal and adapted for automatic orientation over the end of said inner compartment when said carton is squared for loading by the initial abutment of a lower edge of said header panel against the inside of said rear wall, said abutment causing the concomitant rotation of said header panel about its diagonal fold line.
Claim 11
Dependent Claim
43 words
The carton assembly of claim 8 wherein a second header panel is foldably attached to the upper end of said first inner compartment side wall along a diagonally oriented fold line at an interior angle of at least about 30° with the horizontal.
